Is there a way to ajax-update a specific component such as a <h:form>
in backing bean?
I tried the following using RequestContext#execute()
,
RequestContext context = RequestContext.getCurrentInstance();
context.execute("monitorVehicleForm.update()");
however that didn't seem to have any effect.
The RequestContext#execute()
only executes arbitrary JavaScript code which is been passed-in as argument. It does not ajax-update the client representation of the components.
You need RequestContext#update()
instead wherein you just pass the client ID of the to-be-updated component.
context.update("monitorVehicleForm");
This has exactly the same effect as <p:commandXxx ... update="monitorVehicleForm">
. This works provided you've a
<h:form id="monitorVehicleForm">
without any NamingContainer
parent and thus have a
<form id="monitorVehicleForm" name="monitorVehicleForm" ...>
in the generated HTML.
